Description copied from interface: Scope

Scopes a supplier of instances.

This method wraps an unscoped instance supplier with scope-specific logic that controls when new instances are created versus when existing instances are reused.

Specified by:

scope in interface Scope

Type Parameters:

T - the type of instance being scoped

Parameters:

key - the key identifying the instance type

unscoped - the original unscoped instance supplier

Returns:

a scoped supplier that implements the scope's caching strategy

createProxy

protected <T> T createProxy(Key<T> key,
 Supplier<T> unscoped)

dispatch

protected <T> Object dispatch(Key<T> key,
 Supplier<T> unscoped,
 Method method,
 Object[] args)
                       throws Throwable

Throws:

Throwable

getInterfaces

protected Class<?>[] getInterfaces(Class<?> superType)

isTypeAnnotation

protected boolean isTypeAnnotation(Class<? extends Annotation> annotationType)

seededKeySupplier

public static <T> Supplier<T> seededKeySupplier(Class<? extends T> clazz)
